 Out of curiosity, do you get the same output if you use this file instead?
 http://techslides.com/demos/sample-videos/small.ogv



 > Same output whether or not the temporary "Disable Real MIME Check"
 plugin is activated.

 The trouble (at least with the native upload) is `application/ogg` isn't a
 valid MIME type for an OGV file. It is, however, valid for OGX files.
 WordPress is expecting `video/ogg`, and since `application/ogg` presumably
 isn't in your whitelist, it is being rejected. If the OGV example above is
 interpreted correctly, then it might just be that this one particular file
 is misnamed.

 If you have a custom theme on your site, adding the following to its
 `functions.php` should fix it:
 {{{#!php
 function ogx_upload_mimes( $existing_mimes = array() ) {
         $existing_mimes['ogx'] = 'application/ogg';
         $existing_mimes['ogv'] = 'video/ogg';
         return $existing_mimes;
 }
 add_filter( 'upload_mimes', 'ogx_upload_mimes' );
 }}}
